Narrowband heralded single photons via Bragg grating inscription in germanium-doped photonic crystal fiber
Will A. M. Smith, Alex I. Flint, Rex H. S. Bannerman +4
We present a fiber-based source of narrowband heralded single photons in the telecoms C-band. Photon pairs were generated by spontaneous four-wave mixing in photonic crystal fiber…

Phase-sensitive characterization of a quantum frequency converter by spectral interferometry
Mateusz J Olszewski, Kasper Hecht Alexander, Michael T M Woodley +3
We introduce an experimental technique for complete phase-sensitive characterization of arbitrary unitary spectral-temporal transformations of optical modes. Our method recovers th…
